Anatomical terms of neuroanatomy

The nucleus prepositus or nucleus prepositus hypoglossi is one of the largest of the three perihypoglossal nuclei.[1] It is situated in the caudal pons and rostral medulla oblongata.[2] It contributes to several aspects of gaze control including the horizontal gaze holding system.[3]

Injury to the nucleus prepositus results in inability to hold gaze upon a visual target; conjugate eye movement is unaffected.[1]

It may be conceptually regarded as a vestibular nucleus.[2]
